Unit 4B

Sexual and Asexual Reproduction

TermDefinition
Cells Smallest structural, functional, and biological unit of all living organism.
Daughter Cell The result of Mitosis that results in two cells having the same number and kind of chromosomes as the parent cell.
Sexual Reproduction Type of reproduction by which offspring arise from two parents.
Asexual Reproduction Type of reproduction by which offspring arise from a single organism and is produced by mitosis in which the offspring inherit the genes of only one parent.
Gamete Sex cells that are formed by meiosis.
Offspring The product of reproduction.
Genetically Identical Offspring is uniform or an exact copy of the parent.
Chromosomes Thread-like molecules that carry heredity information that are made of protein and one molecule of DNA and most have arranged pairs within the nucleus of the cell.
Mitosis Type of cell division that results in two daughter cells having the same number and kind of chromosomes as the parent cell.
Meiosis A type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells that goes through many phases, and required to produce egg and sperm cells for sexual reproduction.
Gene Basic physical and functional unit of heredity which is made up of DNA.
Binary Fission Fully grown parent cell splits into two halves, producing two new cells, common in prokaryotes, and occurs in some single-celled eukaryotes.
Diverse Offspring The products of Sexual Reproduction that have a genetically unique combination of DNA from both parents.
Uniform Offspring The products of Asexual Reproduction that have genetically identical DNA from a single parent.
Unicellular Organism that is composed of only one cell.
Multicellular Organism that is composed of multiple cells working together.
Fertilization When a sperm enters an ova.
Budding Offspring grows out of the body of the parent (buds).
Heredity The transfer of traits from one generation to another generation.
Mutation A change that occurs in the DNA sequence that are essential to evolution which is the raw material of genetic variation.
Testes The male organ that produces male gametes or sperm.
Ovary The female organ that produce female gametes or ovum.
Vegetative Reproduction A process by which new organisms arise without production of seeds or spores.
Zygote Created when a sperm enters an ova during fertilization where the two gametes fuse and combine their chromosomes to create a unique combination.
Fragmentation The body of the parent breaks into distinct pieces where each piece can produce an offspring.
Regeneration If a piece of a parent is detached, it can grow and develop into a completely new offspring.
